Are the doors on these squares all the same? 73-87. Not sure if I should fix the one I have or replace it.

'73-'76 were a bit different on the inner shell.

They are all interchangeable, when it comes to glass, window tracks, hinges, handles, and latches.

It's just that 73-76 door panels will look goofy on newer doors, but you can retrofit newer ones on older doors with no problem.

The power window regulators don't fit in the '73-'76 doors without modification.

Correct. Power windows started in 77 and the internal structure had to change to accommodate.
So to answer the OP, 77+ are the same.

Oh, my bad, I've never messed with power windows before.

I should also mention that the window crank shaft is longer on later doors than earlier, but they still will bolt in the same.
